German intel warns of direct Russia confrontation; Kyiv claims 51% oil refining disabled

German intelligence chiefs testified to parliament that Moscow is preparing sabotage and murder operations across Europe, signaling a more dangerous phase of confrontation. Separately, Kyiv claims to have disabled 51% of Russia's oil refining capacity and deployed an AI-based automatic firing system to counter new drones. The German warning marks an escalation in official rhetoric, while the Ukrainian claim, if accurate, represents a significant strategic impact on Russian energy infrastructure.
